It took Chuck Pagano less than nine months to instill his fighter’s mentality and hopeful spirit in the Indianapolis Colts. He will need both to survive the biggest battle of his life – leukemia. In a somber news conference Monday, the Colts announced that their new coach had been hospitalized for cancer treatment and probably would not return to full coaching duties this season. He will be replaced on an interim basis by offensive coordinator Bruce Arians. “He will do fine,” Arians said, his voice cracking as he recalled his own fight with prostate cancer in 2007. “I know him. He’s a fighter. He’s survived tough times already in his life. As a cancer survivor myself, I know that these first few days are really hard on you.” New general manager Ryan Grigson read stoically from his prepared notes, and Arians struggled to hold back tears. – AP
